Description

Currently, DockerContainerExecutor will mount "yarn.nodemanager.local-dirs" and "yarn.nodemanager.log-dirs" to containers automatically. However applications maybe need set more environment variables before launching containers.

In our applications, just as the following command, we need to attach several directories and set some environment variables to docker containers.

docker run -i -t -v /data/transcode:/data/tmp -v /etc/qcs:/etc/qcs -v /mnt:/mnt -e VTC_MQTYPE=rabbitmq -e VTC_APP=ugc -e VTC_LOCATION=sh -e VTC_RUNTIME=vtc sequenceiq/hadoop-docker:2.6.0 /bin/bash
